lCE-GREEPER.

To all whom it may concern:

Be it known that l, RUDoLri-r Guerri, a subjectof the King of Hungary, and resident of Martins Ferry, county of Belmont, and State of hio, have invented certain new and useful Improvements in loe- Creepers, of which the following is a specilication.

lhis invention relates to certain new and useful improvements in ice Creepers, and it has for its primary object the provision of a device of this character having novel form, which is instantly adjustable te any of the various shapes and sizes of shoe soles.

A further object of the invention is to provide an ice Creeper which is of simple, durable and economical construction and which possesses a minimum number of parts.

lVith these and other objects in view, the invention resides in the features of construction, arrangement of parts, and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of this speciication, in which- Figure 1 is a perspective view of the invention applied to a shoe sole; Fig. 2 is a top plan view, the casing being shown in section; Fig. 3 is a longitudinal section on the line 3 3, Fig. 2; Fig. l is a cross section on the line H, Fig. Q.; and Fig. 5 is a detail fragmentary view, illustrating one of the spikes er studs.

Referring to said drawings, in which like designating' characters distinguish like parts throughout the several views-1 indicates a casing of substantially tl-shape in cross section which has the free edges of its longitudinal sides 2 bent over inwardly as depicted at 3 in Fig. L1, so as to engage the outer face of the outer bar l of a pair of bars i and 5 which are disposed in superposed relation within the embrace of said casing. Each of the bars t and 5 is formed with an elongated slot G therein through which passes a bolt S having a head 9 in engagement with the outer face of the bar l1- at opposite sides of the slot 6 provided in the latter, and a nut 10 is threaded upon the end'of said. bolt to hind upon the bottoni of casing 1 for maintaining said bars in adjusted relation.

The bolt 8 has a stationary relationship to Speccation of Letters Patent.

the casing, being seated in a perforation provided therefor in the bottom or body portion of the casing. 'lhe adjacent or contacting faces of the bars t and 5 are preferably milled or otherwise roughened, as illustrated in Fig. 8, means being thus provided whereby chance movement of the bars from adjusted position is effectually guarded against.

A pair of oppositely disposed shoe clamps have pivotal connection with the body portion of the device hereinbefore described, each clamp comprising a curved plate 11 having an inte-gral lateral extension 13 located at a point substantially midway between its ends. As shown at the right-hand side of Fig. 3, the extension of one of said clamps has its end disposed between the adjacent ends of the outer bar d and the body of the casing 1 and is pivoted upon a rivetlike pivot-pin 14.- which has its opposite ends held in said ends of the bar l and casing 1, said pivot-pin also serving to maintain said bar and casing in fixed relation. rlllhe eX- tension of the opposite clamp lies, as shown at the left-hand side of Fig. 3, upon the adjacent end of the inner bar 5 and is pivoted upon a rivet-like pivot-pin 15 which is mounted in a stationary position in said end of said inner bar 5 so as to admit of longitudinal movement of said bar and the casing with respect to each other. Fach of the plates 11 stands at substantially a right angle to the position of the base and has formed thereon at points adjacent to the opposite ends thereof shoe-sole-engaging hooks, each consisting of an upright member 12 adapted to lie close against the edge of a shoe sole and terminating in an inturned lip 12a adapted to overlie the solo, as is clearly depicted in Fig. 1. The upright members 12 of said hooks are disposed in any preferred laterally facing position to adapt said hooks for lying closely in engagement with the shoe sole at points more or less widely separated. As is obvious, the pivotal mounting of the clamps adapts the latter' for movement to any position requisite te conform to the curvature of shoe soles of widely varying contours. Each of the clamps has pointed studs or spikes 17 secured thereto in appropriate positions, said spikes being attached by providing same with threaded Shanks 16 for engagement in threaded perforations in the plate ll or by rigidly connecting the parts in any other approved manner.

ln practice, the nut l0 is loosened and the bars and 5 are adjusted longitudinally with respect to each other to cause the clamps to approach or move away from each other, as required. rlaving been adjusted to effect clamping engagement between the hooks and the shoe sole, the nut is tightened to draw the bars 4 and 5 and the casing l` into binding relation for edectively locking all of the parts against movement.

From the foregoing it will be seen that the parts are of simple and economical construction and that to place said parts in condition for immediate attachment, removal, or adjustment, requires the manipulation or" but one part, namely, the nut l0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An ice Creeper comprising a casing of substantially U-shape in cross-section, a pair of longitudinally movable bars disposed in superposed relation within the embrace of said casing and having non-adjacent ends projecting outward from the opposite ends of said casing, said bars having registering longitudinal slots therein in which is received the body of a headed bolt mounted in the casing, sole clamps connected to the projecting ends of said bars t-o be adjustable with respect to each other with movement of said bars, spikes carried by said cramps, and a nut on the outer end of the bolt for binding against the casing.

2. An ice creeper comprising a casing of substantially U-shape in cross-section, a pair of longitudinally movable bars disposed in superposed relation within the embrace oi1 said casing and having non-adjacent ends projecting outward from the opposite ends of said casing, said bars having registering longitudinal slots therein in which is received the body of a headed bolt mounted in the casing, sole clamps having pivotal connection with the projecting ends of said bars, and means acting on said bolt for binding said bars in adjusted position.

3. An ice Creeper comprising a stationary member, a pair of longitudinally movable bars mounted in superposed relation upon said member, each of said bars having an end projected outward beyond the adjacent end of the other, a rivet holding the projecting end of the outer bar in fixed relation to said member, a sole clamp having a portion pivoted on said rivet between the projecting end of said outer bar and said member, a sole clamp pivoted to the projecting end of the opposite bar, spikes carried by said clamps, and means for securing said bars in adjusted relation.

4. An ice creeper comprising a stationary member, a pair of longitudinally movable bars mounted in superposed relation upon said member, each of said bars having' an end projected outward beyond the adjacent end ot the other, a rivet holding the projecting end of the outer bar in fixed relation to said member, a sole clamp having a portion pivoted on said rivet between the projecting end of said outer bar and said member, a sole clamp pivoted to the projecting end of the opposite bar, said bars having longitudinal registering slots therein, a bolt mounted in a stationary position in said stationary member and projected outward through said slots, adjustable means acting on said bolt for binding said bars in adjusted position, and spikes carried by said clamps.

5. In combination with a casing, a spiked clamp pivotally secured to one end of the casing, a bar engaging one end of the clamp and being spaced from the casing, a second bar arranged in the space between the casing and the first named bar and having a longitudinal slot, a spiked clamp pivoted to the outer end of the second named bar, and a nut and bolt connection passing through the casing, the iirst named bar, and the slot the second bar to secure the latter in adjusted position.

6. An ice Creeper including a stationary member having a bolt therein and a clamp pivoted to one end thereof, a bar having a clamp pivoted to one end thereof and having its other end slotted, said bolt passing through the slot in the bar, and a nut on the bolt to bind the bar to the stationary member.

ln testimony whereof l aiiiX my signatur in presence of two subscribing witnesses.
